Buy this if you own a wood stove
Wow ! We bought a new wood stove and I round spring type thermometer for it. For months we thought our stove was over firing and tried everything to have the stove cooler. We adjusted the doors, adjusted the ash door and had a chimney flue installed. Nothing worked so we were talking about selling it and buying a different brand of wood stove. We then had 2 different wood stove technicians look at it. They both said get rid of that cheap dial thermometer and buy a infrared thermometer. So we then bought this Mestek thermometer. OMG ! Unreal! The difference between the 2 thermometers were unbelievable. When are dial thermometer was showing 1,000° this infrared thermometer was showing 625°. It is put on mind ease. We are not up for hours at midnight trying to get the stove to cool down. For the first time since we bought this wood stove we now love it. What a saving grace buying this infrared thermometer was. Thank you Mestek for you wonderful product ! We highly encourage anyone with a wood stove to buy this thermometer.

All mentioned functions are work. One point, its reading is different vs Klein tools.

Exactly What I Was Looking For To Check My Epoxy!
This Infrared Thermometer Gun is exactly what I was hoping it would be. I do a lot of resin & wood art and knowing proper temps not only in my room, but of the actual epoxy is crucial for some of my experiments & projects that I am doing. Some of the techniques requiring waiting until your epoxy reaches a certain temp., probes are messy with resin, become a hassle, sometimes it starts curing & you have to toss them out or they become inaccurate. I really didn't want to shell out more money for a temp gauge but I am sure glad I did. Just the time this is saving me & the Prime Day Deal made it all worth it. This one I can literally point it at the surface & get a pretty darn close reading. It's been accurate for the most part every time. Comes with very thorough & complete instructions. There's so much to this product and I haven't even used all of its capabilities as of yet & I may never use them all LOL but knowing that they are there when I need them gives me peace of mind! Added probe attachment is a great bonus feature! Construction of unit is solid, durable housing. Not flimsy. Comes with a holster style case to keep it clean & dust free when not in use. They even included the 2 AA batteries, cheapy ones, but nonetheless they are there to get you started. Looks & feels comfortable in your hand. Grips nicely. Size is perfect. It's not overly huge, fits in a drawer, tool bag, shelf, closet, etc. without taking up a lot of room. I have a feeling I will be getting a lot of use out of this way beyond the craft room. So many things you can check the temperature of & will come in handy for that you don't even realize, At $39.99 (at time of posting this, 10/16/25) I feel it's a little, teeny bit on the high side. I feel most budget-conscious consumers will pass this by but the quality may be worth the investment on this product! Definitely Recommend!!

Great purchase!
My husband built a brick oven and loves this tool. It helps him figure out what temperature he’s at, and has said he would definitely recommend it.

Well-made, easy to use, and accurate
I can't believe I waited so long to get this. It was purchased so I could get an accurate temp on our flat top griddle and it works great. Now that I have it, I find uses for it all the time.

Works just as well as much more expensive options
This gauge works great and for the money it's a good buy. I've compared it with another more expensive gun that I have and all the results were similar so I see no reason to pay more.
